Comment (by nbruin):

 From experience I know that if you are going to run a different python,
 you'll have to set PYTHONPATH and PYTHONHOME to the appropiate (previous)
 values too. I ran into this problem with a start-up script (in python) for
 magma. It didn't use anything fancy from Python, but at some point my
 system python and sage python (or their c-libs) were sufficiently
 different that the sage python libraries (picked up via PYTHONPATH, which
 was normally unset on my system) prevented python from running
 successfully.
